About Omnitek

U-VIsc Kinematic Viscometers

The OmniTek U-VIsc combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis.

While offering full compliance with ASTM D445/446, the specially designed viscometer tubes cover a 100-fold range, e.g. from 1 to 100 mm2/s.

Available models:


U-VIsc 110


U-VIsc 120


U-VIsc 210


U-VIsc 220


  • Compliant with requirements for ASTM D445, D446 and related specifications
  • Very easy to use and maintain
  • Single or dual solvent injection to meet any application requirement
  • High throughput: up to 40 samples per hour
  • Advanced touch screen
  • Fully functional as a stand-alone unit but advanced PC software available
  • Easy tube exchange. Back to work in minutes without the need for a service tech
  • No external vacuum required
  • Chemically resistant to allow for all common solvents
  • Thermal / optic detection available to meet any application requirement
  • Sampling using vacuum or pressure allows analysis of volatile samples
  • Optional fast-run tubes further reduce solvent consumption and increase throughput
